Application led January 16, 1928. Serial lo. 247,193.

This invention relates to al device for the production of cushions.

An object of the invention is the provision of a device for supplying anupholstery ller in piping which is adapted to be employed for use in.cushions for automobile seats.

A further object of the invention is the provision of a device providedwith a tube through which portions of travelling belts are adapted tomove for forcing the filler into a piping which is mounted on the tubewith means being provided for removing the filled piping progressivelyas the fllleris fed into said piping.

This invention will be best understood from a consideration of thefollowing detailed description in connection with the accompanyingdrawings; nevertheless, it is to be understood that the invention is notconfined to the disclosure being susceptible of such changes andmodifications as shall define no material departure from the salientfeatures of the invention as expressed in the appended claims.

In the drawings Figure 1 is a vertical section ofthe ma chineconstructed according to the principles of my invention,

Figure 2 is a front end view of the uphol stery machine,

Figure 3 is a rear end view in elevation of the machine,

Figure 4 is aI fragmentary vertical section showing the supports for thetable.

Referring more particularly to the drawings and 11 designate sidemembers of a frame which are adapted to be secured to the floor of abuilding, and to support the essential features of the upholsterymachine. Secured to the side members in any approved manner is a tube 12having the outer ends, as shown at 13 and 14, open through which areadapted to move endless belts 15 and 16. These belts are trained,respectively, around pulleys 17 and 18 mounted for rotation at the outerend of the tube and also trained, respectively, around pulleys 19 and 20mounted for rotation in brackets 21 extending rearwardly from the framemembers 10 and 11. The last mentioned pulleys are located adj acent theinner open end 14 and are provided with spikes 22 adapted to engage thebelts 15 and 16 for causing synchromzed movements `is mounted in a yoke26 carried by the arm 27 which is slidable in a guide 28 secured to aframe Vbar 10 or 11, as the case may be. A lever 30 is pivotally mountedat 31 on a bracket 32 and is provided with a weight 33 at its outer freeend and connected by means of a pin 34 and a slot 35, to the arm 27. Theweight of the member 3 3 forces the pulley 25 at all times intoengagement with the belt 16.

A second series of belt tighteners in the form of pulleys 40 arerotatably mounted, respectively, in yokes 41. Each yoke is carried by anarm 42 slidably mounted in a guide 43 secured to a frame bar 10 or 11. Alever 45 is pivotally mounted at 46 and is connected to the arm 42 bymeans of a pin 47 and a slot 48. A link 49 connects one `end of a lever50 with one end of the lever 45 and the lever-,50,being pivoted at 51 toa bracket 52 which'extends laterally from a frame bar 10 or 11. Thelever 45 is likewise pivoted on the bracket 52. A Weight 53 is securedto one end of the lever 50 and tends to maintain the roller 40 inenga-gement with the belt 15. The link 49 is provided with pins 60 and61 adapted to be received within slots 62 and 63, respectively.

A table is slidabl mounted beneath the pair of tubes 12 and as dependinglegs 71 provided with a roller 7 2 in the free end thereof, moving inguides 73. Located in alignment and in parallel relation with the legs71 are a second set of legs 74 which rest upon a moving belt 75 and aremaintained in place by means of cleats 76 and spaced suficiently apartto receive the lower free ends of legs 74. n

A belt 75 is trained over pulleys 77, 78 and 79 and is driven by meansof a pulley 20 vhicli is driven in synchronism with the pul- Pulleys 19and 20 are driven through a pair of cooperating gears 80 and 81, andgear 81 is rotated by means of a crank 82 secured to a shaft 83 uponwhich the pulleys 20 are mounted.

It will be noted that pairs of tubes 12 together with theircorresponding endless belts 15 and 16 and pulleys 19 and 20 are mountedrelative to the table 7 0 so that a pair of pipings may be supplied withthe filler simultaneously. While I have shown two tubings, 1t will beappreciated that a plurality of such tubings may be employed forincreasing the production.

The operation of my device 1s as follows:

The filler is fed between the rollers 19 and 20 which is 'carriedthrough the open end 14 of the tube 12 by means of the belts 15 and 16,until it reaches the outer end 13 of the tube 12 where it is forced intoa pipe 90 located in telescoping relation with the tube 12 and also withthe outer portions of the belts 15 and 16. Since the outer portion'ofthe belts move inwardly it will tend to move the. piping inwardly andthus retain said piping in taut relation with the tube 12 so that saidpiping may be properly filled while the innerfpor-l vtions of the belts15 and 16 move the filler into prising a frame, a filler tube mounted onthe frame and adapted to support a piping, endless belts trained throughand around the tube, means for driving the belts, means for feeding afiller to a portion of the belts moving into the tube, said beltscarrying the filler to the opposite end of the tube and forcing the sameinto a piping.

2. A device of the character described comprising a frame, a filler tubemounted on the frame and adapted to support a piping, endless beltstrained through and around the tube, means for driving the belts, meansfor feeding a filler to a portion of the belts moving into the tube,said belts carrying the filler to the opposite end of the tube andforcing the same into a piping, and means for removing the pipingprogressively from the tube.

3. A device of the character described comprising a frame, a filler tubemounted on the frame and adapted to support a piping, endless beltstrained through and around the tube, means for driving the belts, meansfor feeding a filler to a portion of the belts mov ing into the tube,said belts carrying the filler to the opposite end ofthe tube andforcing the same into a piping,-a table mounted for movement, said piing bein connected with the table so that w en the ta le is movedoutwardly from the filler tube, the piping will be progressivelyremovedfrom said tube.'

4:. A device of the character described comrising a frame, a filler tubemounted on the rame and adapted to support a piping, endless beltstrained through and around the tube, means for driving the belts, meansfor .feeding a filler to a portlon of the belts moving into the tube,said belts carrying the filler to the opposite end of the'tube andforcing the same into a piping, the inner or feeding end of the tubebeing expanded.

5. A device of th-e character described comprising a frame, a. fillertube mounted on the frame and adapted to support a piping, endless beltstrained through and around the tube, means for feeding a filler to aportion of the belts moving into the tube, said belts carrying thefiller to the opposite end of the tube and forcing the same into apiping, rollers carried by the outer end of the tubing for supportingthe belts in spaced relation, and rollers located adjacent the oppositeend of the tube for supporting and driving the belts.

6. A device of the character described comprising a frame, a filler tubemounted on the frame and adapt-ed to support a piping, endless beltstrained through and around the tube, means for feeding a filler to aportion of the belts moving into the tube, said belts carrying thefiller to the opposite end of the tube and forcing the same into apiping, rollers carried by the outer end of the tubing for supportingthe belts in spaced relation, and means for maintaining the belts taut.

7 A device of the character described comprising a frame, a filler tubemounted on the i frame and adapted to support a piping, endless beltstrained through and around the tube, means for feeding a ller to aportion of the belts moving into the tube, said belts carrying thefiller to the opposite end of the tube and forcing the same into apiping, rollers carried by the outer end of the tubing for supportingthe belts in spaced relation, and rollers located adjacent the oppositeend of the tube for supporting and driving the belts, means forsynchronizing the movement of the table with the feeding belts.
